With Copy and Paste and MMS Support now out of the way, Multitasking on the iPhone (non-jailbroken) remains one of the most sought after and desirable features for the next major OS update. While it has been rumored that OS 4.0 will implement some form of multitasking, AppleInsider has just reported that the 4.0 software will indeed allow 3rd party apps to run in the background. To switch between apps, users will experience something similar to Mac OS X’s Expose interface:

Those familiar with the design of iPhone 4.0 said that the user interface will resemble Apple’s desktop Expose feature, in that a key combination — reportedly hitting the Home button twice — will trigger an expose-like interface that brings up a series of icons representing the currently running apps, allowing users to quickly select the one they want to switch to directly. When a selection is made, the iPhone OS zooms out of the Expose task manager and transitions to that app.

When Multitasking does come to fruition for the iPhone, users will no longer have to complain about lagging behind other smart phones that DO support it. So, will Apple eventually cave in and allow for flash on the iDevice? Only time will tell.
